Solution
1. Remove the spark plug. Reattach the spark
plug cap and lay the spark plug on the metal
cylinder. Pull the starter grip and rope and
watch for a spark at the spark plug tip. If
there is no spark, repeat the test with a new
spark plug.
2. Push primer bulb until the bulb is full of
fuel. If the bulb does not fill, the primary
fuel delivery system is blocked. If the primer
bulb fills, the engine may be flooded. (See
next item.)
3. Remove the spark plug. Turn the product
so that the spark plug hole is aimed at the
ground. Make sure the choke lever is set to
RUN and pull the starter grip and rope 10
to 14 times. This clears excess fuel from the
engine. Clean and reinstall the spark plug.
With the trigger fully depressed, pull the
starter grip and rope 3 times. If the engine
does not start, set the choke lever to FULL
and follow normal starting instructions. If
the engine still fails to start, repeat the pro-
cedure with a new spark plug.
4. Contact a qualified service dealer.
1. Use fresh fuel and the correct 2-cycle oil
mix.
2. Clean the air filter.
3. Clean the spark arrestor.

2. Install more line.
3. Pull line while alternately pressing down on
and releasing the retaining cap.
